Use the following chart as a guideline for estimating material requirements (based upon pounds of material needed for 100 feet of cracks):
The above coverage rates are only a guideline. Actual material usage may vary due to width of application and thickness of material above pavement surfaces.
CrackMaster™ 5078 is a hot-pour crack and joint sealant for portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, CrackMaster™ 5078 prolongs pavement life by sealing cracks and surface joints from water penetration. CrackMaster™ 5078 is a single component, specially formulated mixture of paving grade asphalt, vulcanized crumb rubber, plasticizers, and stabilizers. When melted and properly applied, it forms a resilient and adhesive compound for both cement and asphaltic pavements.
CrackMaster™ 5078 is recommended for sealing cracks and joints in portland cement, asphaltic pavements, and parking lots. It is designed to seal expansion and contraction joints, longitudinal and transverse cracks, joints between concrete and asphaltic shoulders, and random cracks.
Use material as supplied. Do not blend with other materials. After CrackMaster™ 5078 is melted it should be agitated or recirculated.
Apply heated CrackMaster™ 5078 using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e. 2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8″ above surrounding pavement. Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.
Protective apparel is recommended with application of CrackMaster™ 5078. The extremely hot material will cause severe burns on contact with skin. OSHA Safety Regulations require workers to wear the following types of safety attire (see current OSHA/Safety Regulations for additional information): Hard hat with face shield; long sleeved shirt buttoned at the wrist; heat resistant gloves; long, cuffless pants; and safety toed work boots. Make certain all area around melter is clear of all debris and flammable materials. Avoid breathing vapors. Use with adequate ventilation.
Wash tools in water before material dries.
